The 57 Dense Concrete Blocks are rectangular shaped made of grey-coloured concrete, have a rough finish and weighs 18 kg. Measures 440mm in length, 215mm in width, and 100mm in height. Left over from a build and have the odd mortar splash on from the brickie but they have not been used. I will be away from 17th to 26th April, it may not be possible to collect during this period.
